ReCooler HP

ReCooler HP

The ReCooler HP is an integrated reversible cooler. 
Depending if the air handling unit is in heating or cooling 
demand the ReCooler HP will alter between cooling and 
heating mode.

Defrost fan compensating

Under some conditions the ReCooler HP will go to a defrost 
mode during a couple of minute. During this time the 
fans will go on reduced speed. This reduced fan speed 
is configurable for each fan. The settings are 20-100 % of 
actual fan setpoint.

as the cooling/heating demand and the actual operating 
status. If there is an alarm in the ReCooler HP, it could be 
viewed in the eQ display.
